“…After rainfall, the internal water content of the slope increases, the unsaturated zone decreases, and the submerged surface rises as shown in Figure 7. Studies have shown that as the soil water content increases with rainfall, the matrix suction decreases and the hydrostatic pressure increases, the effective stress in the soil decreases, which leads to slope instability [46]. In the soil plastic strain cloud map (Figure 8), the red section represents the location with the largest sliding displacement and high probability of destruction [40].…”

Rainfall-prone shallow landslides account for one-fifth of the global land area, and rainfall is critical to the mechanics and hydrology of shallow slopes. In typical geological disaster-prone areas, the hydrodynamic responses of slopes with different vegetation types under rainfall conditions require further study. The purpose of this study was to analyze the hydraulic stability of soils with different vegetation types under rainfall conditions and their effects on slope stability. Thus, the soil–water characteristic curves and water-stable aggregate characteristics of soils with three vegetation types were analyzed. A two-dimensional finite element model was used to simulate the slope stability of extreme rainfall environments with different rainfall durations. The results showed that the matric suction of soil with trees was less affected by rainfall with a better stability of water-stable aggregates than that of soil with shrubs and grass. The plastic strain cloud map showed that the maximum plastic strain occurred at the toe of the slope. In addition, the potential slip depth of slopes with trees was smaller than that of slopes with shrubs and grass. Under the two rainfall durations, the factor of safety (FoS) of slopes with trees changed by 0.06, whereas that of slopes with shrubs and grass changed by 0.1. The findings of this study provide valuable insights into changes in the stability of slopes with different vegetation types under varying rainfall conditions. It is of great significance to provide a scientific basis for the application of ecological measures in the prevention and control of mountain disasters and guide the implementation of appropriate land management measures.

“…The topic of landslides is widely studied from various disciplines (Shanmugam and Wang, 2015). But, reports and publication of landslides mostly described the process and qualitatively analyzed the role of water and clays which causes less friction coe cient along the sloping rock body (Wu et al, 2017;Saito et al, 2017;Wu et al, 2016;Alsubal et al, 2019). Other studies mostly only do landslide dynamics modeling, perform simulations to gain knowledge of how the transport process in landslides (Li et al, 2012;Dai et al, 2014;Shi et al, 2016).…”

Alluvial cliff with high slope and step has been known to cause curving sliding plane. This phenomenon is adopted as a knowledge, but it has never been studied theoretically. In this paper, mathematics derivation phenomenon is proposed using special model of 11 fracture criterion ????-????. The quantity of ???? is A???? 2 with A is a friction coefficient of stress ???? 2 . The failure model was substituted to the corresponding Mohr circle resulting the expected curve. The curve was used to measure the observed field profile to obtain the friction coefficient A.
